I am little bit desperate because I do not have idea what is happening. I setup network like the picture shows:
There is vDSL cable internet from provider. Connection is distributed to other 2 routers.
The problem is that sometimes when notebooks are connected to wifi, there is DNS problem - pages can not be loaded - chrome showing Resolving address.
However if I connect directly to router by cable, there is no problem with DNS and internet is working fine.
All router has manualy set dns to google 184.108.40.206
Do you have any advice what can cause the problem and how to solve it? Thanks
